Feature/Command | Support | Comments |
Adaptive Compression System | New | Adaptive compression system enables the printer to |
|
| compress internal raster data when memory becomes low. |
|
| This operation occurs automatically; there are no PCL |
|
| commands for this feature (refer to Chapter 5 for ADC |
|
| information). |
Configuration Command | New | Allows PCL jobs to be printed (using LocalTalk or |
|
| EtherTalk MIO) using AppleTalk protocol. |
Number of Copies | Modified | Supports |
|
| printer. |
Units of Measure Command | New | Allows selection of the units of measure for cursor moves, |
|
| drawing rules, and for character spacing (font metrics). |
Page Size | Modified | A parameter value is added for B5 envelope size; the HP |
|
| LaserJet 4 printer supports the four standard paper sizes |
|
| and five envelope sizes. |
Bitmap Font Support | New Header | Printer will expand 300 dpi bitmap fonts to 600 dpi. A new |
|
| 300/600 dpi bitmap font descriptor has been added to |
|
| allow bitmap fonts to be created that work at either 1/300 |
|
| or 1/600 inch printer resolution. |
Scalable Font Support | New Header | A new Universal header has been added to allow design of |
|
| typefaces of different scaling technologies to be supported |
|
| by one header. This header is used to support TrueType on |
|
| the HP LaserJet 4 printer. (This header will be used to |
|
| support any other new scaling technologies HP may add in |
|
| the future). |
True Type | New | TrueType scaling technology support has been added to |
|
| the printer. |
Internal Typefaces | New | Several new Intellifont and TrueType internal typefaces |
|
| (and supporting symbol sets) are now provided in the |
|
| printer. |
Raster Resolution Command | Modified | Parameter values have been added to support raster |
|
| resolutions of 200 dpi and 600 dpi. |
New Header | A new 300/600 dpi | |
|
| added to support patterns that work at either 1/300 or |
|
| 1/600 inch printer resolution. |
